I have recently come across a "new kind" of cheating for me.... I have seen it happen to others and also to me. Most recently, a player got a penalty on rule 10 (port/starboard). The player then decided not to complete the course, but to ruin mine. He went on to disturb my wind for the rest of the race, hence significantly hurting my result. As he had not passed the buoys, he was "ghosted", so I could not do anything to make him go away. But his wind shadow still has an effect. As I said, I have seen this a few times this week (not before). Any idea what to do with this ? Its really despicable..
